Changes in Thermal Physiology with Advancing Age
The functional capacity of the thermoregulatory system can be shown to alter with ageing and this is believed to underly the reduced resistance of elderly people to excessively cold or warm ambient temperatures.1 The lability of thermal homeostasis appears to be an important factor in the increased incidence of cases of urban hypothermia during the winter in the UK2 and the summer epidemics of heat stroke in the elderly in cities in the United States.3 There is, however, little detailed knowledge of thermoregulatory impairment as a concomitant of the ageing process. Investigations have therefore been made of the control and function of different aspects of the thermoregulatory system in healthy elderly as compared with young individuals.
